What does this mean for design, well for me its a single column layout thank you very much.
I wanted to comment specifically on this. I typically design documents in sections. Each of those sections is positioned accordingly. Some are absolute, some are relative. Serving multiple stylesheets based on media makes it easy for me to take the main stylesheet, make a few adjustments and have a totally different layout without changing existing markup. You can serve different images, change widths and heights, overall layout, etc.
You could easily take a 2, 3 or even 5 column layout and convert it to mobile friendly (visually) with just a few simple changes to the main stylesheet. You position the document sections to best serve your visitors. Since I work with Source Ordered Content, I've found the conversion for different media to be a rather simple process.
Again, all you do is take the main stylesheet, copy it, and make your revisions from there. You can hide specific content, you can move stuff around easily, you are not constrained by layout at all. Think of your document in sections that can be positioned anywhere you want them to be with the switch of a stylesheet.
I just can't see going through all the maintenance that would be involved in serving a different site under another host name or at the directory level. There's a risk that one day someone will accidentally remove the noindex, nofollow and next thing you know you're battling with duplicate content. And then you'll have folks linking to that content and I don't think you want to split your equity in that manner - do you?
